Henry III of Castile sends Ruy González de Clavijo as ambassador to Timur to discuss the possibility of an alliance between Timur and Castile against the Ottoman Empire.
Ruy Gonzlez de Clavijo (died 2 April 1412) was a Castilian traveler and writer. In 1403-05 Clavijo was the ambassador of Henry III of Castile to the court of Timur, founder and ruler of the Timurid Empire. A diary of the journey, perhaps based on detailed notes kept while traveling, was later published in Spanish in 1582 (Embajada a Tamorln) and in English in 1859 (Narrative of the Embassy of Ruy Gonzalez de Clavijo to the Court of Timour at Samarcand AD 1403-6).
Henry III of Castile (4 October 1379 – 25 December 1406), called the Mourner (Spanish: Enrique el Doliente, Galician: Henrique o Doente), was the son of John I and Eleanor of Aragon. He succeeded his father as King of Castile in 1390.
